Specification of Letters Patent. Patentgd Sept, 1, 1914:.

Application filed November 7, 1908. Serial No. 461,566.

lb all whom it may concern lie i known that 1, MAX GorILKE, a subject oftheliinperor of Germany, residing at Berlin, in the Empire of Germany,have invented certain new and useful Improvements in Ball-Bearings, ofwhich the fol-- I both radial and end thrusts, or substantially anycombinations thereof, the casing elements of each pairbeingdisc'onnected from each other. I l H 'lhe drawing represents across-section through a bearing embodying my invent-ion,

the same being applied to a shaft, which lat- 'teris shown in elevation.

Referring to the drawings, my improved bearing comprises a series ofrolling members l, in the present instance anti-friction balls, whichare mounted between two pairs of annular casing elements or rings, onepair comprising an outer ring 6 and an inner ring 0, by which the radialthrusts are transmitted to the rolling members, and the other paircomprising opposing rings d and e, by which the thrust loads aretransmitted to the rolling members, there being thus four casingelements so disposed that the interposed rolling members will take bothradial and thrust loads.

The bearing is shown as applied to a shaft f, and giving rotary supportto the same within a surrounding supporting member 9, the casingelements 0 and 61 being applied to the shaft while the other casingelements, 6 and e, are applied to the supporting member. The supportingmember 9 is provided with an annular surface g to receive the casingelement Z) and with an annular shoulder 9 to receive the casing element6; while the inclosed shaft f is provided with an annular shoulder 7b toreceive the casing element {Z and with a surface f to receive the casingelement 0, the several casing elements by this means being given firmand continuous support both radially and endwise.

In their adjacent faces, the several casing elements are provided Withraceways or grooves, to formtracks for the rolling members, and from theedges of the grooves," the sides of the casing elements slope or incline"outwardlyfrom eachother, whereby the two pairs of rings are adapted tofit or dovetail into each other, with-the result that the raeeways willconjointly surround substan tially the entirecircumference of the balls,

sufficient clearance being left between these,

sloping sides to permit full load supporting contact between theraceways and balls without interference by the engagement of the slopingsides of the'casing elements with each other. The inner casing element 0is shown as mounted between an upper collar 7L and a lower collar i onthe shaf the collar in being extended outwardly, and affording a seatfor the casing element cl; Under these conditions, a thrust load on theshaft, in a downward direction, will be transmitted by the collar h toring (Z, and by it transferred to the rolling members, whence it will betransmitted to the casing element e, and finally received by thesurrounding supporting member 9. The radial loads will be transmitted bythe casing element 0 to the rolling members, in a direction at rightangles to the direction of the thrust load, and by the rolling memberswill be transmitted to the outer casing element 3), and finally receivedby the surrounding supportingmember 9.

It is to be understood that my improved bearing is not limited in itsapplication to the particular form of parts shown, but may be employedwith the same functions and effects in connection with other parts, andwherever it is desirable to take care of radial and thrust loads. It isfurther to be under stood that the invention is not limited to anyspecific form or arrangement of parts, except in so far as suchlimitations are specified in the claim.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States is as follows:

In combination with a rotary member or shaft provided with an annularshoulder and with a supporting surface, a surround ing supporting memberprovided with an annular supporting surface and with an annularshoulder, a casing element applied to the supporting surface of theshaft, a casing element applied to the supporting surface of thesupporting member, a series of interposed balls tracking onsaid casingelements and acting in connection with'them to take wardly from theirball contact surfaces, 10 radial loads, a casing element applied to thewherebythe opposing casing elementsv will shoulder on the shaft, and acasing element fit into eachother. applied to the shoulder on thesupporting In testimony whereof Iaifix my signature 5 member and formedwith ball tracks, saidin presence of two Witnesses.
